>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: fs/azure
>    Affects Versions: 3.4.0, 3.4.1
>            Reporter: Manika Joshi
>            Assignee: Manika Joshi
>            Priority: Major
>              Labels: pull-request-available
>
> The legacy WASB driver has been deprecated and is no longer recommended for 
> use. To support customer onboard for migration from WASB to ABFS driver, 
> we've introduced a script to help with the configuration changes required for 
> the same.
> The script requires the configuration file (in XML format) used for WASB and 
> would generate configuration file required for ABFS driver respectively.
